“…Lee and coworkers identified related lignans including 30 - 33 (Lee et al 2009). Lignans are ubiquitous secondary metabolites with special significance in many gymnospermous plant families, such as Oleaceae, Linaceae and Asteraceae (Ward 1995, Umezawa 2003, Schmidt et al 2010, Szokol-Borsodi et al 2012, Boldizsar et al 2010 a & b, Solyomvary et al 2015). They are also present in other species of genus Myristica , such as the dilignan argenteane, 34 , isolated from the mace of M. argentea (wild or false nutmeg) and the lignan ketone 1-oxo-otobain isolated from M. simarum (Calliste et al 2010, Kuo et al 1976).…”

Nutmeg is a valued kitchen spice that has been used for centuries all over the world. In addition to its use in flavoring foods and beverages, nutmeg has been used in traditional remedies for stomach and kidney disorders. The antioxidant, antimicrobial and central nervous system effects of nutmeg have also been reported in literature. Nutmeg is a rich source of fixed and essential oil, triterpenes, and various types of phenolic compounds. Many of the secondary metabolites of nutmeg exhibit biological activities that may support its use in traditional medicine. This article provides an overview of the chemistry of secondary metabolites isolated from nutmeg kernel and mace including common methods for analysis of extracts and pure compounds as well as recent approaches towards total synthesis of some of the major constituents. A summary of the most significant pharmacological investigations of potential drug leads isolated from nutmeg and reported in the last decade is also included.

“…Monolignols can also give rise to more than 3,000 different lignans and associated structures such as neo-, sesqui-, and flavanolignans (Schmidt et al, 2010). Lignans are optically active phenylpropanoid dimers that result from the stereo-selective dirigent protein-mediated coupling of the 8 and 8′ C-atoms of two hydroxycinnamyl alcohol (monolignol) moieties (Davin et al, 1997).…”

Plants are built of various specialized cell types that differ in their cell wall composition and structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterized by the presence of the heterogeneous lignin polymer that plays an essential role in their physiology. This phenolic polymer is composed of different monomeric units – the monolignols – that are linked together by several covalent bonds. Numerous studies have shown that monolignol biosynthesis and polymerization to form lignin are tightly controlled in different cell types and tissues. However, our understanding of the genetic control of monolignol transport and polymerization remains incomplete, despite some recent promising results. This situation is made more complex since we know that monolignols or related compounds are sometimes produced in non-lignified tissues. In this review, we focus on some key steps of monolignol metabolism including polymerization, transport, and compartmentation. As well as being of fundamental interest, the quantity of lignin and its nature are also known to have a negative effect on the industrial processing of plant lignocellulose biomass. A more complete view of monolignol metabolism and the relationship that exists between lignin and other monolignol-derived compounds thereby appears essential if we wish to improve biomass quality.

“…Linum species have been used as the source of fiber (L. usitatissimum L.), seed oils, fodder and ornamentals. Flax seed oils contain omega-3 fattyacids and anticancer compounds (Rogers 1982), while lignans have been identified in flowering aerial parts of these species (Schmidt et al 2010).…”

The genus Linum L. (Linaceae) has more than 200 species. These species have agricultural, industrial, and medicinal importance. Domestication and continuous selection reduce genetic diversity of plants and in order to develop new and improved varieties, we should utilize all available genetic diversity in that crop and its wild relatives. The cultivated flax (L. usitatissimum L.) is an important crop plant and is being evaluated as a crop platform for the production of bio-industrial and nutraceutical products. In present study, we studied 230 plants of 23 populations in four Linum species namely, pale flax (L. bienne Mill.), cultivated flax (L. usitatissimum L.), and two wild relatives, L. austriacum L. and L. album L. The objective of this study was to investigate population genetic structure and genetic variability within each species using SSR and EST-SSR markers.The low degree of genetic variability was obtained in these species. AMOVA revealed significant genetic difference among species and populations. The significant correlation was observed between genetic and geographical distances the studied species. Evanno test and K-Means clustering revealed genetic fragmentation in the studied Linum species. Networking and STRUCTURE analysis revealed genetic affinity of the populations. The population assignment test revealed absence of gene flow or the occurrence of very limited gene flow among populations.
